I'm uploading a bunch of files with the upload module. Everything went smoothly until I tried to upload a compressed file with a .tar.gz file. The upload itself was successful but I get this message upon finishing:

"For security reasons, your upload has been renamed to test.tar_.gz."

The original file name was test.tar.gz but Drupal somehow thought it was a security risk and went ahead and renamed it for me. (It added an underscore after 'tar'.) I tried other .tar.gz files but had the same result.

Could I override this behavior without resorting to modifying upload module?

Shortly after posting the above inquiry, I found my own solution. I DID look into the php scripts in hope of figuring out what's going on.

It turns out the error message was generated by a function named file_munge_filename() located in file.inc. Basically what it does is when there is a string whithin a file name that resembles a file extension that is not allowed, an underscore will be added.

I solved the problem by going to administer->site configuration->file updates and then adding tar to the list of permitted extensions.
